Magnetic resonance imaging of the liver. Standard and proposed abbreviated protocols. 66-year-old man with 30-mm hepatocellular carcinoma (HCC) imaged with standard gadoxetate disodium protocol (a) and proposed abbreviated protocols for HCC screening. Gadoxetate disodium may be administered outside the scanner 20 min before abbreviated protocols that contain a hepatobiliary phase (b-d) or an extracellular agent can be administered before dynamic phases (e). Abbreviated protocols may include T2-weighted single-shot (SS) and hepatobiliary phase (HBP) (b); T2-weighted SS, diffusion-weighted imaging (DWI), and HBP (c); DWI and HBP (d); or pre-contrast and arterial, portal venous, and delayed phases (e). ECA, extracellular contrast agent; HBA, hepatobiliary contrast agent
